support: Exit on consistency check failure in resolv_response_add_name 

Using TEST_VERIFY (crname_target != crname) instructs some analysis
tools that crname_target == crname might hold.  Under this assumption,
they report a use-after-free for crname_target->offset below, caused
by the previous free (crname).
